Floating figures and tables

2015-10-1 14:56:51 阅读106 评论0 12015/10 Oct1



常用选项[htbp]是浮动格式:

『h』当前位置。将图形放置在正文文本中给出该图形环境的地方。如果本页所剩的页面不够,这一参数将不起作用。
『t』顶部。将图形放置在页面的顶部。
『b』底部。将图形放置在页面的底部。
『p』浮动页。将图形放置在一只允许有浮动对象的页面上。

一般使用 [htbp] 这样的组合,只用 [h] 是没有用的。这样组合的意思就是 latex 会尽量满足排在前面的浮动格式,就是h-t-b-p 这个顺序,让排版的效果尽量好。

优先级从 h 到 p 逐个递减,首先考虑 h 选项,万不得已才用 p 选项。

选项 !h 只是试图放在当前位置。如果页面剩下的部分放不下,还是会跑到下一页的。一般页言,用
